Tanami Rd sealing a 'good investment'

State and federal politicians have thrown their support behind a plan to seal the Tanami Road.

The proposal has been discussed for years but has gained momentum with the release of an economic impact study commissioned by the Shire of Halls Creek.

It indicates that sealing the Alice Springs to Halls Creek road would quickly pay itself off via increased tourism and mining activity and a reduction in freight costs.

Western Australia's Member for Mining and Pastoral, Ken Baston, says the project would also generate jobs, making it a win-win situation.

"The costs are all levelled up and it's very interesting that in the impact statement, the cost of upgrading this road is some $160 million, and yet they've come out with a benefit of $570 million, so to me that's a pretty good investment," Mr Baston said.
